My clutch has started to slip, only currently noticeable when accelerating uphill, from 3rd up. Revs jump with power loss. No issues in 1st or 2nd so far, though I'm taking it easy. Is this likely to gradually get worse, or just fail completely very suddenly? I'm trying to work out how soon I can get it in to the garage I use... it's W reg 1.7l if that helps, can't remember current milage off the top of my head (wanna guess 110k-ish?) no idea if the clutch has been replaced before. I'm assuming this is clutch rather than anything else! Any previous experience or helpful suggestions welcome
